How do I get files on disk, not just the file size in Java?

I need the file size on the disk, not the file size

File myFile = new File ("C:\\Send\\Capture.png");

        System.out.println((int)myFile.length());

^This code gives the file size I need the file size on the disk They are always different, as shown in the figure below, right?

Solution

Look at link

The answer is c# provided, but because it uses Win32 API functions, you can easily convert it to Java The function used to get the disk size is getcompressedfilesize

Hope to help
